Introduction — A useful brief identifies the product, user, environment, constraints and

decisions that development must resolve. Before development begins, the team

should distinguish confirmed requirements from assumptions that still need evidence.

Background — Product work loses clarity

when commercial aims, use

conditions and technical requirements

are mixed without priority.

Key Judgments — Definition should establish scope before styling detail, and

every open assumption should remain visible for review.

• Decisions about
• range, components
• and performance
• should
• be

recorded against the use case that justifies them.

Working Method — Clarify users and use, map the product system, define materials and construction, then record the review gate. A practical sequence is to confirm the brief, identify unresolved questions, align the product architecture and assign an owner to each decision.

Common Risks — Vague scope, hidden assumptions and premature supplier requests create avoidable revisions and inconsistent quotations. Risk rises when reference images

are treated as specifications or when different stakeholders use the same term for different outcomes. Undefined user and

use environment. Conflicting product boundaries. Unverified material assumptions. Styling decisions without construction context. Supplier requests issued before review.

Practical Deliverables — The practical output is a reviewed product definition covering scope, components, materials, construction intent and open decisions. Definition Record Scope statement The product boundary and intended outcome are written in terms a supplier and internal reviewer can interpret consistently. Use conditions User, environment, care, storage and performance expectations are separated

from visual preference. System map Garments, components or softgoods are organized so dependencies and exclusions are visible. Decision log Confirmed choices, assumptions and open questions are assigned a status and review owner. Review gate Development proceeds only when the definition is coherent enough to support the next technical decision.

package. The next note explains how controlled information supports quotation, sampling and review.
